Tabstack Founding GTM Lead, Mozilla

• The ideal candidate has the heart of a developer but the mindset of a founder
• You are comfortable in a "0 to 1" environment with minimal support, eager to experiment, and willing to get your hands dirty in everything from writing integration docs to negotiating contracts
• 5+ years of relevant experience: A mix of Product Marketing, Technical Sales, Founder experience, or Developer Relations with a heavy focus on revenue/growth
• Technical Fluency: You must be able to speak the language of AI engineers. You don’t need to be a core contributor, but you should understand the mechanics of browser automation, APIs, and the current LLM landscape
• The "Hustle" of a Founder: Experience working in early-stage startups or new product incubators. You know how to generate leads without a massive marketing budget
• Strong Communication Skills: Proven ability to produce clear, accessible technical writing (docs, blogs) and persuasive business communications (decks, outreach emails)
• Deep Industry Knowledge: Understanding of the modern AI stack (LangChain, LlamaIndex, vector DBs) and the browser automation space (Puppeteer, Playwright, Selenium)
• Commitment to our values:
• Welcoming differences
• Being relationship-minded
• Practicing responsible participation
• Having grit
